SPECIFICATION forming part of Letters Patent No. 476,760, dated June 7,1892.

Application filed February 23, 1892. Serial No. 422,481. (No model.)

To all whom it may concern:

Be it known that we, ROBERT AUGUSTUS PANCHAUD, secretary, residing at 43Great Tower Street, in the city of London, and UL- LIAM GEORGE TEMPLE,mechanic, residing at 80 Malden Road, London, in the county ofMiddlesex, England, subjects of the Queen of Great Britain and Ireland,have invented certain Improvements in Apparatus for Drawing Off orDispensing Aerated Liquids, of which the following is a specification.

This invention relates to apparatus for drawing oft or dispensingaerated liquids in which the aerated liquid is drawn from the mainreservoir into an intermediate vessel from which gas-pressure is thenrelieved, and then the contents of the said intermediate vessel aredrawn off at a reduced pressure into a glass or vessel for consumption.

The object of thisinvention is to utilize the pressure in the aeratedliquid itself when first introduced from the main reservoir to theintermediate vessel to effect the closure of the said intermediatevessel, after which the communication between the main reservoir and theintermediate vessel is closed, and then the pressure in the said vesselis reduced by allowing a portion of the gas to escape, and then theoutlet from the intermediate vessel automatically opens to discharge thecontents thereof.

Ive will describe, with reference to the accompanying drawings, what weconsider the best method of carrying this invention into effect,premising, however, that we do not limit ourselves to the precisedetails shown.

Figure 1 is a vertical section (on the line 1 3, Fig. 3) of an apparatusconstructed according to our invention, the parts being shown in thepositions which they occupy when the liquid under pressure is beingadmitted to the intermediate vessel. Fig. 2 is a vertical section takenalong the line 1 2 in Fig. 3, the parts being shown in the position theyoccupy when the intermediate vessel is empty or being discharged. Fig. 3is a plan of the valve boX, the valve being removed so as to show thepassages in the valve-seat; and Fig. 4 is a face view of the valve,showing the ports or passages therein.

A is a pipe communicating with the reserflange c is pressed against thewasher Z1 as shown, or in any other con vcnient way. The

pipe A communicates with the passage a in the valve-seat D, whichpassage, when the valve E is in the position shown in Fig. 1,communicates by a radial passage b in the valve E with a passage 0 inthe valve-seat and leading to the interior of the vessel 0.

Connected to the under side of the valveseat and communicating with thepassage 0 is a tube or cylinder F, containing a piston d, provided witha hollow piston-rod G, through which and through the piston passes a rodor stem 6, which passes loosely through the passage in the said pistonand piston-rod, a space being left between the stem 2 and the interiorof the hollow rod G and piston 61 for the passage of liquid, ashereinafter described. The stem 6 is provided at its upper end with avalve f, which normally closes the passage through the piston andpistonrod, and carries at its lower end aplug or stopper g for closingthe outlet from the vessel G. Then the vessel O is empty and the valve Eis in the position shown in Fig. 2, liquid cannot enter the said vessel0, and the piston 01 and valvef are maintained by the spring lat theupper end of the cylinder F, as shown in Fig. 2, the valvef being closedupon its seat in the said piston cl. hen the valve E is in thisposition, the interior of the vessel 0 is in communication with theexternal atmosphere by passages t' i in the valve-seat D, connectedtogether by the passage is in the valve E, the passage 2' leading to theinterior of the vessel and the passage 1' being open to the atmosphere.The spindle E of the valve E is provided with a handle E, by which thevalve may be turned in the direction and to the extent required. WVhenthe handle E is turned into the position shown in Fig. 1, the liquidunder pressure will pass from the reservoir through the pipe A andpassages a, b, and 0 into the cylinder F, and the pressure thereof, byacting on the piston d and its valve f, will cause them to descend,thereby compressing the spring Z and forcing the plug or stopper ICO 9into the discharge-opening h of the vessel 0. The pressure, still actingon the piston (1, causes it to descend still farther, it then slidingindependently of the stem 6 away from the valve f, thereby opening thepassage in the piston d and piston-rod G, through which passage theliquid will pass and through openings m in the lower end of thepiston-rod into the vessel 0 until the vessel has filled or has receivedits required supply.

To deliver the liquid from the vessel 0 for consumption, a glass orother suitable receptacle is placed beneath the discharge-opening h andthe valve E is turned by means of the handle E into the position shownin Fig. 2, so as to cause the passage 7c in the valve to connect thepassage 2' 2' and the passage a to be closed by a solid portion of thevalve, so that the communication between the reservoir and vessel 0 iscutoff and gas-pressure above the liquid in the vessel 0 is allowed toescape into the atmosphere through the passages '6, 7c, and 2 Thepressure in the vessel being thus reduced, the piston d, under theaction of the spring l, rises in the cylinder F, and, coming intocontact with the valve f, lifts the rod 6 and raises the plug g out ofthe dischargeopening h. The liquid will then flow from the vessel 0 atthe required reduced pressure into the receptacle placed in position toreceive it in a sparkling and fresh condition and without unduesplashing.

In the u'pperend of the cylinder F orin the nozzle by which it isconnected to the valveseat D is a small opening at, through which theliquid contained in the cylinder F above the piston 01 passes into thevessel C as the piston rises in the cylinder. The apparatus may be fixedto a counter or other suitable support, and the pipe leading to thereservoir may be inclosed in a tubular bracket H, as shown, or beotherwise concealed.

The foregoing arrangement provides a large passage for the liquid to theintermediate vessel after the valve g is closed. The arrangement can besimplified Without, however, the advantage of the said large passage ifthe piston be made solid and its rod be provided with the valve g, ahole, as at n, alfording a passage for the liquid under pressure fromthe cylinder F to the vessel C, the said hole being sufficiently largefor the purpose, but not so large as the inlet-passage a b a, so thatthe'liquid is admitted to the cylinder F at a greater rate than that atwhich it passes therefrom by the hole 12, and therefore the requisitepressure is obtained to close the valve g.
